## Convert OTP to PPSX in Python

[**Aspose.Slides for Python via Java**](/slides/python-java/) can load an OpenDocument Presentation Template (OTP) and save it as a PowerPoint PPSX slide show. PPSX is the XML-based PowerPoint Show format and is intended to open directly in slide show mode in compatible applications. The conversion does not require Microsoft PowerPoint, LibreOffice, or OpenOffice.

## Convert OTP to PPSX using Python

Create a `Presentation` from the OTP file and call `save` with `SaveFormat.Ppsx` to create the PPSX slide show.

### Python code for converting OTP to PPSX

```python
presentation = Presentation("presentation.otp")
try:
    presentation.save("presentation.ppsx", SaveFormat.Ppsx)
finally:
    presentation.dispose()
```
